interests therein) purchased pursuant to the Tranche 3(a) Purchase, Tranche 3(b)
Purchase or Tranche 3(c) Purchase, for a period of [***]* after the last day of
the month in which the first, second or third anniversary of the Initial Closing
Date occurs, respectively, (iv) transfer, sell, assign, pledge, grant a security
interest in or otherwise dispose of any Shares (or interests therein) purchased

transfer is in compliance with applicable securities laws. Each of the periods
described in Sections 4.1(a)(i), (ii), (iii) and (iv) during which the
applicable Shares are not transferable are hereinafter referred to as the
"RESTRICTED PERIODS". In the event that any Subsequent Closing Date does not
occur by [***]* following the final day of the period covered by the Measurement

specified in Section 4.5(b), (2) any dispute under Section 4.5(d) that results
in a change in the Revenues reported in such Revenue Report of [***]*, or (3)

applicable Restricted Period will be extended by one day for each day that the
Subsequent Closing is delayed beyond [***]* for any such reason.

     (b)  At no time shall the Purchaser sell, assign, pledge, grant a security
interest in or otherwise dispose of any Shares (or interests therein) without
appropriate registration and qualification under the Securities Act and the
state securities laws of any applicable jurisdiction, unless an exemption from
the registration requirements of the Securities Act and such securities laws is
available and the Purchaser has provided to the Company (at the Purchaser's
expense) an opinion of counsel to the Purchaser in form and substance reasonably
satisfactory to the Company that such exemption is available, which opinion (i)
may be from the Purchaser's internal counsel, and (ii) may assume all matters of
fact.

     (c)  Each of the certificates representing the Shares purchased by
Purchaser pursuant to this Agreement (the "CERTIFICATES") will bear a legend to
the effect set forth below, and appropriate stop transfer instructions against
the Shares will be placed with any transfer agent of the Company to ensure
compliance with the restrictions set forth herein.

     THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
     SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR
     OTHER JURISDICTION AND MAY NOT BE TRANSFERRED, SOLD, OFFERED FOR SALE,

     OF COUNSEL TO THE HOLDER OF THE SECURITIES OR OTHER EVIDENCE, REASONABLY
     SATISFACTORY TO THE COMPANY AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT
     REQUIRED.

In addition, the Certificates will bear any legend imposed or required by
applicable state securities laws.

     (d)  The Company will replace, at its own expense, any Certificate
representing Shares with a certificate not bearing the legends required under
Section 4.1(c), if (i) such Shares have been registered and sold pursuant to an
effective registration statement under the Securities Act, (ii) such Shares then
held by the Purchaser may be sold under Rule 144(k) of the Securities Act
without restriction after expiration of the applicable Restricted Periods, or
(iii) such Shares otherwise no longer constitute "Restricted Securities" (as
defined in Rule 144 of the Securities Act).

     (e)  For purposes of this Agreement:

          (i)   "AFFILIATE" shall mean, with respect to any person, any other
person directly or indirectly controlling, controlled by, or under direct or
indirect common control with, such person; and

for the resale by the ADP Holders (as defined below) of the Additional Shares
[***]* (each, a "REGISTRATION STATEMENT"), provided, however, that the Company
shall not be obligated to effect any such registration, qualification or

     Re:  Common Stock Purchase Agreement, dated as of June 11, 2001, by and
          between Exult, Inc., and Automatic Data Processing, Inc.

Ladies and Gentlemen:

     We have acted as special counsel to Exult, Inc., a Delaware corporation
("EXULT"), in connection with the Common Stock Purchase Agreement dated as of
June 11, 2001 (the "AGREEMENT"), by and between Exult and Automatic Data
Processing, Inc., a Delaware corporation (the "PURCHASER"). This opinion is
delivered to you pursuant to Section 5.2(h) of the Agreement in connection with
the Initial Closing. Pursuant to the Agreement and subject to and upon the terms
and conditions set forth therein, on the date hereof Exult is selling and
issuing to the Purchaser, and the Purchaser is purchasing from Exult, 1,538,461
shares of Exult's common stock, par value $.0001 per share (the "PURCHASED
SHARES") at a purchase price of $13.00 per share in cash. Except as otherwise
indicated herein, capitalized terms used in this opinion have the meanings
ascribed to them in the Agreement.

     In connection with this opinion, we have examined and relied upon the
representations and warranties as to factual matters contained in and made
pursuant to the Agreement by the parties thereto, and originals or copies,
certified to our satisfaction, of such records, documents, certificates,
opinions, memoranda and other instruments as in our judgment are necessary or
appropriate to enable us to render the opinions expressed below.

     Except as expressly stated otherwise herein, whenever our opinion herein
with respect to the existence or absence of facts is stated to be to our
knowledge or known by us, such statement is intended to signify that during the
course of our representation of Exult, as described herein,


--------

* Confidential information has been omitted.


                                      A-1
<PAGE>   26

no information has come to the attention of the lawyers in our firm working on
the transactions contemplated by the Agreement that would give us actual
knowledge of facts contrary to the existence or absence of the facts indicated.
However, we have not undertaken any independent investigation to determine the
existence or absence of such facts, and no inference as to our knowledge of the
existence or absence of such facts should be drawn from our representation of
Exult.

     Based upon the foregoing and in reliance thereon, and subject to the
assumptions, qualifications, exceptions and limitations herein contained, as of
the Initial Closing Date we are of the opinion that:

     1.   The Agreement constitutes a legal, valid and binding obligation of
Exult, enforceable against Exult in accordance with its terms.

     2.   The execution and delivery of the Agreement by Exult, and the
performance by Exult of its obligations under the Agreement and the consummation
of the transactions therein contemplated, will not result in (i) a breach of any
of the terms of Exult's certificate of incorporation or bylaws, or (ii) a
material breach of any United States federal or New York laws applicable to
Exult or any of its subsidiaries or, (iii) to our knowledge, a material breach
of any judgment, order or decree of any court, arbitrator or administrative or
governmental body applicable to Exult or any of its subsidiaries.

     3.   Except as set forth in the Agreement, no consent, approval, order or
authorization of, or filing with, any governmental body or, to our knowledge,
any nongovernmental person or entity, is required on the part of Exult or any of
its subsidiaries in connection with the transactions contemplated by the
Agreement.

     4.   When issued in accordance with the Agreement and after Exult's receipt
of payment for the Purchased Shares, the Purchased Shares will be duly
authorized, validly issued and outstanding, fully paid, and non-assessable.

     5.   Subject to the accuracy of the representations and warranties made by
the Purchaser in the Agreement, the offer, issuance, sale and delivery of the
Purchased Shares as contemplated by the Agreement is exempt from the
registration requirements of the Securities Act of 1933, as amended.

     Notwithstanding anything in the foregoing opinions to the contrary, the
foregoing opinions are subject to the following exceptions, qualifications and
limitations:

     A.   We have assumed (i) the genuineness of all signatures, the
genuineness, authenticity and completeness of all documents submitted to us as
originals, the conformity to originals of all documents submitted to us as
copies, and the genuineness, authenticity and completeness of the originals from
which such copies were made; (ii) with respect to agreements and instruments
executed by natural persons, the legal competency and authority of such persons;
(iii) the due authorization, execution and delivery of the Agreement by each of
the Purchaser and Exult, whether or not due authorization, execution and
delivery is a prerequisite to the effectiveness thereof; (iv) that each of the
Purchaser and Exult has the power, authority, legal competency and legal right
to enter into and perform the terms and conditions to be performed


                                      A-2
<PAGE>   27

under the Agreement; (v) that the Agreement is the binding obligation of the
Purchaser, enforceable against the Purchaser in accordance with its terms; and
(vi) that the Purchaser has not taken any action, is not omitting and has not
omitted to take any action, that would constitute a material breach or a default
under the Agreement.

     B.   We have assumed that there are no documents, agreements,
understandings or negotiations between Exult and the Purchaser which would
expand, modify or otherwise affect the respective rights and obligations of the
parties set forth in the Agreement and that the Agreement correctly and
completely sets forth the intent of all parties thereto.

     C.   Our opinion is subject to (i) the effect of applicable bankruptcy,
reorganization, insolvency, moratorium, arrangement or other similar laws and
court decisions of general application affecting creditors' rights generally
(including, without limitation, the effect of statutory or other laws regarding
fraudulent conveyances or transfers or preferential transfers or distributions
by corporations to stockholders); and (ii) general principles of equity,
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing and the possible unavailability of specific performance,
injunctive relief or other equitable remedies, regardless of whether
enforceability is considered in a proceeding in equity or at law.

     D.   We express no opinion as to (i) any provision of the Agreement
requiring written amendments or waivers of such documents insofar as it suggests
that oral or other modifications, amendments or waivers could not be effectively
agreed upon by the parties or that the doctrine of promissory estoppel might not
apply; (ii) the validity or effect of contractual provisions providing for
severability or imposition or waiver of penalties or damages; or (iii) any
waiver of the right to jury trial.

     E.   We express no opinion with respect to the legality, validity, binding
nature or enforceability of any provision of the Agreement to the effect that
the election of some particular remedy does not preclude recourse to one or more
others or that failure to exercise or delay in exercising rights or remedies
will not operate as a waiver of any such right or remedy.

     F.   We express no opinion as of the legality, validity, binding nature or
enforceability of (i) provisions prohibiting competition, the solicitation of
employees, the use or disclosure of information, or other provisions relating to
activities in restraint of trade; (ii) waivers or advance consents that have the
effect of waiving statutes of limitation; (iii) any provisions which are found
by courts to be against public policy or (iv) any waivers which are ineffective
pursuant to applicable statutes and judicial decisions.

     G.   No opinion is expressed as to the legality, validity, binding effect
or enforceability of any provision of the Agreement regarding the remedies
available to any party (i) to take discretionary action which is arbitrary,
unreasonable or capricious, or is not taken in good faith or in a commercially
reasonable manner, whether or not such action is permitted under the Agreement,
or (ii) for violations or breaches which are determined by a court to be
non-material or without substantial adverse effect upon the ability of a party
to perform its material obligations thereunder.


                                      A-3
<PAGE>   28

     H.   With respect to the opinions expressed in paragraph 5 above, we
express no opinion as to compliance with the antifraud provisions of federal
securities laws.

     I.   We render no opinion herein as to matters involving the laws of any
jurisdiction other than (i) the federal laws of the United States of America;
and (ii) the laws of the States of Delaware and New York. We are not admitted to
practice in the State of Delaware; however, we are generally familiar with the
Delaware General Corporation Law as presently in effect and have made such
inquiries as we consider necessary to render the opinion expressed above. This
opinion is limited to the effect of the current state of the laws of the United
States of America and the States of Delaware and New York and to the current
judicial interpretations thereof and to the facts bearing upon this opinion as
they currently exist. We assume no obligation to revise or supplement this
opinion in the event of future changes in such laws or the interpretations
thereof or such facts.

     This opinion is furnished by us as special counsel to Exult and is solely
for your benefit in connection with the Agreement and the transactions
contemplated thereby. Without our prior written consent, this opinion may not be
relied upon by you for any other purpose or by any other person. This opinion
may not be quoted, in whole or in part, or copies thereof furnished, to any
other person without our prior written consent, except that you may furnish
copies hereof (a) to your independent auditors and attorneys; (b) to any state
or federal authority having regulatory jurisdiction over you; (c) pursuant to
order or legal process of any court or governmental agency; and (d) in
connection with any legal or governmental action, proceeding or investigation to
which you are a party arising out of the transactions contemplated by the
Agreement.

                                                     Very truly yours,


                                                     [***]*

Automatic Data Processing, Inc.

     Re:  Common Stock Purchase Agreement, dated as of June 11, 2001, by and
          between Exult, Inc., and Automatic Data Processing, Inc.

Ladies and Gentlemen:

     I am General Counsel to Exult, Inc., a Delaware corporation ("EXULT"). In
that capacity, I am delivering this opinion to you pursuant to Section 5.2(h) of
the Common Stock Purchase Agreement dated as of June 11, 2001 (the "AGREEMENT"),
by and between Exult and Automatic Data Processing, Inc., a Delaware corporation
(the "PURCHASER") in connection with the Initial Closing. Except as otherwise
indicated herein, capitalized terms used in this opinion have the meanings
ascribed to them in the Agreement.

     In connection with this opinion, I have examined and relied upon the
representations and warranties as to factual matters contained in and made
pursuant to the Agreement by the Purchaser, and originals or copies, certified
to my satisfaction, of such records, documents, certificates, opinions,
memoranda and other instruments as in my judgment are necessary or appropriate
to enable me to render the opinions expressed below.

     Based upon the foregoing and in reliance thereon, and subject to the
assumptions, qualifications, exceptions and limitations herein contained, as of
the Initial Closing Date I am of the opinion that:

1.   Exult is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware, and has the requisite
corporate power and authority to execute and deliver, and perform its
obligations under, the Agreement, and to consummate the transactions
contemplated thereby.

2.   Exult has taken all corporate action required to authorize its execution
and delivery of and performance of its obligations under the Agreement, and the
consummation by it of the transactions contemplated thereby. The Agreement has
been duly executed and delivered by Exult.

3.   Subject to paragraph A below, the execution, delivery and performance by
Exult of the Agreement, and the consummation of the transactions contemplated
thereby, will not result in any breach of or default under any material
mortgage, indenture, lease, contract or other agreement or instrument, permit,
concession, franchise or license to which Exult, any of its subsidiaries or any
of their respective properties or assets are subject as of the date hereof,
other than such breaches or defaults which will not have a Material Adverse
Effect.

4.   To my knowledge and without any investigation of court records, there is no
claim, litigation or investigation pending or threatened against or involving
Exult before any governmental entity that (i) questions the validity of, or the
obligations of Exult under the Agreement, or (ii) seeks to impede, enjoin or
invalidate the transactions contemplated by the Agreement.
